Unique SSV DN125 and DN150
Unique Single Seat DN125 (5") and DN150 (6") valves are pneumatic seat valves in a hygienic and modular design offering a wide field of applications, for instance as a stop valve with two or three ports or as a change-over valve with three to five ports. These valves complement the Unique Single Valve family for large size installations in specific areas of your plant where size matters.
Versatile and reliable single seat valve
Alfa Laval Unique single seat valves (SSVs) are robust and reliable pneumatic seat valves that are supremely reliable and versatile.
Modularity provides cost-effective and nearly endless possibilities for purpose-built seat valves that meet high standards of hygiene. Configure the Unique SSV valve bodies, plugs and actuators to meet virtually any requirement.
Superior valve process safety
The Unique SSV range is built on a proven modular platform used on more than a million valves in service worldwide. Pressed from a single stainless steel disc, the valve body is extremely strong and durable, thus ensuring production safety. The enhanced performance of the actuator makes operation safer and more efficient.
Greater valve durability
To ensure high sealing quality, the Unique SSV range features defined compression of the O-rings with metal-to-metal contact between plug and seat. This significantly reduces wear and extends valve service life. The standard Unique SSV is supplied with a semi-maintainable actuator that has a five-year warranty.
Low total cost of ownership
Thanks to its straightforward, reliable design, the Unique SSV range provides long service life, reduced product loss, greater product safety and more processing uptime. Few moving parts reduce service requirements and inventory costs. More effective CIP procedures with reduced cleaning cycles and, subsequently, the reduced use of cleaning fluids, water and utilities also contribute to the Unique SSV’s low total cost of ownership.
